Introduction The RS-485 bus is widely used in industrial communication, but harsh industrial environments can lead to external interference, such as Electrical Fast Transients (EFT), which affect its stability. This article explores how to test and mitigate the interference of EFT on the RS-485 bus. Sources of Pulse Group Interference In industrial control environments, disturbances … Read more
Abstract In the wave of bus-type alternatives, major automation manufacturers have launched their own bus-type motion control products. Among the various types of bus communications, EtherCAT stands out remarkably. According to MIR Rui Industry statistics, as of 2021, the market size of bus-type motion controllers in China exceeded 6 billion, accounting for more than 70% … Read more
Ethernet (Ethernet) is a well-known type of network, created by Xerox and jointly developed by Xerox, Intel, and DEC as a baseband LAN specification. It is the most widely used communication protocol standard for existing local area networks, including standard Ethernet (10Mbit/s), Fast Ethernet (100Mbit/s), and 10G (10Gbit/s) Ethernet. PROFIBUS is an international, open, and … Read more
1. Basic Properties of PROFIBUS PROFIBUS specifies the technical and functional characteristics of the serial fieldbus system. Through this system, distributed, digital field programmable controllers can be networked from the lower level (sensor, actuator level) to the middle level (unit level). PROFIBUS is divided into master and slave stations. > Master Station The master station … Read more
